This is the title of the philosophically most relevant book of primatologist Frans de Waal (1996). Now we get to the point I mentioned before: that during 95,5% of all the time that our species can be considered human, our ancestors lived as gatherers-hunters. In these millions of years, our human nature has been formed. In the most recent eight thousand years (0,5% of our history) that we have been living as settled farmers, our original gatherer-hunter nature has been frustrated, but not wiped out.

First, something about a question that has been much debated in the last few thousand years of philosophy: is human nature intrinsically good or bad? Many philosophers from the past, for example Plato or Hobbes, tended to the second option. In many forms of religious belief, for example ultra-orthodox Protestantism, an inherent badness – sinfulness – of human nature is postulated as well. On the other hand we have had philosophers, such as in the 18th century Enlightenment, who opted for a positive – sometimes even naively positive – view on human nature: just let Reason reign, install true democracy, and everything will be alright. Both views on human nature are simplistic and one-sided because implicitly, they are based on moral presumptions about what constitutes “good” versus “bad” behavior.

In more modern philosophy, the trend is rather to avoid such moral presumptions about human nature. Modern philosophy has often (and not always in a fruitful manner) been reduced to playing with words and abstractions, while claiming to not being able to contribute much when it comes to moral matters. Whether we like it or not, by avoiding such moral positions, modern philosophy does no longer function as the moral beacon it once, alongside religion, was in human society and has made itself in a social sense largely irrelevant.

As for the anthropologists, they too seem to follow a pessimistic philosophical view on human nature. In the 1950s, shortly after World War II, among them the “killer ape hypothesis” of anthropologist Raymond Dart was influential. According this hypothesis, war and interpersonal aggression was the driving force behind human evolution. Science writer Robert Ardrey expanded on this idea in African Genesis (1961), suggesting that the urge to act violently was a fundamental trait of the human mindset. Ethologist Konrad Lorenz also emphasized this pessimistic view of human nature with his book On aggression (1966). According Lorenz, animals, particularly males, are biologically programmed to fight over resources. Movies such as Planet of the Apes (1968) show that this issue affected popular opinion[1]. In 1996, Wrangham and Peterson followed the Dart/Lorenz trail in their influential book Demonic Males, suggesting an evolutionary connection between violent chimpanzees and violent man. However, in the same year the Dutch/American ethologist Frans de Waal countered with his influential book Good Natured.

The reader will already understand that the humanosophic view follows the latter view. Wrangham and Peterson even presume that our H. erectus ancestors deceived others and waged wars. We think that war emerged simply as the result of overpopulation: as the consequence of a social, not an inherent problem. H. erectus groups were sparse and needed each other for their survival. When two groups met each other, this was more reason for feast than for war: the groups needed each other for interchanging experiences and partners, and presumably for handing out sparks of fire[2]. As for the deceiving, we already presumed that H. erectuses were sign language communicators, for whom deceiving is more difficult: with body language, it would mean having to hold many muscles under more conscious control, which is difficult even for present-day sign language communicators.

Other convincing concrete evidence of our assumption of peacefulness is furnished by the most primitive people of present-day mankind: the scarce little populations of pure gatherer-hunters, like the Inuit and the San people. If it had been our ancestors’ nature to deceive each other and to wage wars, then these last of the gatherer-hunters would demonstrate a similar war-faring culture. But on the contrary, these are very peaceful people.

Many of the other primitive groups we know today, like the Yanomamö in the Amazon area and the Mountain Papuans in New Guinea, are not just gatherer-hunters anymore but rather horticulturalists. These groups live in a totally other situation than the gatherer-hunters: a situation of overpopulation, since too many groups have to share limited resources. This situation leaves them no other choice than to fight for survival. It is such overpopulation that forced them to give up the pure gatherer-hunter lifestyle. But in the long run of human history, this overpopulation is a relative recent phenomenon.

Human nature as we view it, is a three-stage rocket. The first stage we share with all living creatures, even with bacteria and plants. It is the individual drive to take as much energy as possible from the environment to stay alive and procreate. It is this self-centered survival drive that still gets the upper hand in real or imagined panic situations.

The second stage: our ancestors were group animals. By living in a group they were able to extract energy, to stay alive and procreate, in a more efficient way than an individual. Theoretically there are three kinds of groups: firstly the insect-groups like ants or bees where the individual is no more than a component of one collective organism, secondly the herd-groups like swarms of fishes or sparrows, and herds of zebras or buffaloes[3], and in the third place the social groups of highly self-conscious animals such as elephants, dolphins and apes.

We are apes, so for our second stage we have to look to the group animals and especially to the bonobos and chimpanzees: our next of kin. In the permanent survival fight between their groups, chimpanzees have an individual interest in being a member of the strongest group. To keep their group strong, they must minimize the internal fights. When two chimpanzee males do have a fight, then afterwards they try desperately to reconcile. Bonobos use sex for minimizing internal group tensions.

These group animals to which we humans belong, are driven by two contradictory impulses: egoism (the me-myself-and-I drive) and altruism (you have more chances to survive and to pass on your DNA in an harmonious group, so you must curb your egoism). These two impulses are at right angles to each other and would condemn individuals to a paralyzing indecision if they did not have a calming mechanism at their disposal: manners, rules for social intercourse, culture, ‘norms and values’. Basically this mechanism is present with all group animals,[4] and in a more complex manner, similar mechanisms still keep us humans together. In moralistic philosophy, the two opposite impulses (altruistic vs. egoistic) often correspond with concepts of good and evil.

This ‘norms and values culture’ only works within a coherent group. It does not extend across different groups: in fact, it is a form of egoism-as-a-group. It does allow aggression and violence against any other groups. But we saw that the groups of Early Humans were small (about 25 individuals) and rare, and so they needed each other. During the countless centuries that our ancestors were Homo, there was rarely any reason or opportunity for aggression and violence between groups at all. The groups needed each other for their survival: for exchange of sex partners, knowledge and experience. When two of these groups met, it was occasion for a feast.

However, as for the moralistic good and evil,how should we label violence against other groups of the same kind? Good or evil? So we have to define what is ‘good’. Good is what is conducive for the survival. For the individual survival? Then purely egoistic, self-centered behavior would be ‘good’! But usually such behavior is not good for the group as a whole: from the group perspective, such egoistic behavior is ‘evil’! So ape groups developed ‘norms and values’, developed a primitive form of morality: for a group animal, goodis behavior that is conducive for the survival of the group.

As for the third stage of the human nature rocket, our ancestors developed a social norms and values culture that extended beyond the limits of one’s own group: as long as our ancestral Early Humans were pure gatherer-hunters, they were are able to behave as noble wilds, living in harmony with their natural environment, with each other, and even with other human groups. And because that long-long time has determined our human nature, we are still noble wilds in our deepest desires. For humans, harmony is good.[5] ***It is the result of natural selection: in the harsh environments groups with harmony flourished more than quarreling groups. After thousands of generations, inclination to harmony became an innate tendency.

We still long for harmony, we still feel that being kind to each other is the most livable basis for society. Since we became AMHs (the last 100.000 years after 2 million years of being gatherer-hunters) this basic social feeling got perhaps somewhat frustrated when larger groups of 150-200 individuals evolved. But it only got frustrated totally after we became horticulturalists, with all the warfare and machismo that this recent lifestyle implied. The lowest point was reached in the class-based societies since 5000 years ago, with slavery, mass cruelties and monotheism.

Today we have a chance for recuperation. The unique quality of humanity is that we are capable of reflection. This capability may be seen as a further refining step on the path of extracting energy from the environment and of passing-on DNA. On the basis of reflection we may become aware that all groups of humans have the same interest: surviving on the planet Earth. Beyond our own planet, there is no alternative place available for extracting our energy and for passing-on our DNA. Once we see the need for it, we humans have the capability to make the next step beyond group harmony: global harmony between all our groups.

Our universal basic story, the science-based new ‘creation story’, may serve as an essential building stone for this reflection.

So are Wrangham & Peterson wrong with their Demonic Males? No, not wrong, but biased and overlooking the long-long evolutionary human history of low population density that repeatedly brought us to the verge of extinction. Wrangham & Peterson and their adepts see only ‘stage’ 1 and 2 as human nature. They are obviously ignorant of the peaceful nature of our longtime pure gathering-hunting existence, unaware of the more recent effects of overpopulation, and therefore unacquainted with the overall historical development of human nature.
